Hey there,
Your question states: Which choice most effectively displays the concept of comparison and contrast?
Based on my understanding, the best option from your answers choices above,your correct answer would be [tex]\boxed{D}[/tex]. My reason on why I say that the answer would be "While they are almost the same size, Earth and Venus have very different terrains." is basically because this would be a good compare and contrast. The other options have no click to it to make a concept of making a compare and contrast. Your correct answer would be D.
Correct answer : "While they are almost the same size, Earth and Venus have very different terrains"
